Recombination and Meiosis Models, Means, and Evolution /

Once per life cycle, mitotic nuclear divisions are replaced by meiosis I and II reducing chromosome number from the diploid level to a haploid genome and recombining chromosome arms by crossing-over. In animals, all this happens during formation of eggs and sperm in yeasts before spore formation. Th...
